APPARATUS FOR THE AUTOMATIC MANIPULATION 0F METAL INGOTS AT ROLLING-MILLS.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed July 7, 1919. Serial No. 309,131.

T 0 all whom it may concern:

Be it known that I, EVAN WALTER DAVIES, a subject of the King of GreatBritain and Ireland, residin at Dowlais, in the county ofGlamorgansliire, Wales, have invented certain new and usefulImprovements in Aparatus for the Automatic Manipulation of l etal Ingotsat Rolling-Mills, of which the a specification.

This invention relates to appliances for the automatic manipulation ofmetal ingots and the like at rolling mills and refers to improvemnts inor modifications of apparatus of the type for which Letters Patent havebeen granted to me Nos. 15117, dated 24th June, 1914, and 113225, dated13th July, 1917, in Great Britain.

With apparatus of the type in question, as hitherto constructed, whereit has been desired to turn ingots of manydifferent 'sizes and shapes,through a large range of angles, the mechanism has been complicated, andcostly, and the object of my present invention is to provide acomparatively simple apparatus which is adapted to turn ingots and thelike varying, greatly in size and shape through a large range of angles.

According to my present invention, I so construct and/or mount theturning or receiving members that they are adapted to give the ingot orbloom two successive turning movements, and to eifect this I constructthe turning or operating member so that it moves about two independentpivots or their equivalents in succession, while nevertheless the saidturning member may be of extremely simple construction, consistingpreferably of one or two parts only.

As regards the receiving member, that is, the member for holding theingot or the like while the operating member is giving it the turn, Imay construct this from two counterbalanced plates, one of which holdsthe ingot during the first portion of the turning movewhich is somewhatbehind the first mentionedplate, holds the ingot or the like While it isbeing turned through a further amount of arc.

, Asian alternative, I mayprovide a coun terbalanced receiving plate or.plates, so shaped that the ingot to be turned first comes into contactwith an advanced or projecting portion thereof, after which it comesinto contactlvvith another portion of the said plate, which gives it asecond turning move- One of ment. For enabling a large range of sizes tobe dealt with I prefer to mount the turning and receiving members sothat the pivots are adapted to slide in slots, the result being thatoperating and receiving members can automaticall ad'ust themselves fordealim y l r member for holding the ingot. during the process ofturning, constructed according to the present invention, the turningmember itself or operating member being of the type illustrated in thedrawing accompanying my British specification No. 113225.

Fig. 2 is a detailed side view of a modified form of the ingot-receivingmember.

Figs. 8, 4 and 5 are vertical longitudinal sectional views showinganother modification of the invention, with the ingot or bloom atdifferent stages of the turning operation.

Figs. 6 and 7 are also vertical sectional views of still furthermodifications relating more particularly to the clutch turning member.

Fig. 8 is a detailed side view of a still further modification relatingmore especially to the ingot or bloom receiving member.

Fig. 9 is a partially side and sectional view of a still furthermodification of the invention. a V

' Figs. 10 and 11 are side elevations of still further modificationrelating more particularly to the bloom receiving member.

a indicates the level of the conveying rollers, b is the cross. head forthe receiving member, and c is the casing of the cross head of theoperating member. These (Toss heads are controlled in the ordinarymanner by piston rods;

03 and (Z are two counterbalanced plates,

one mounted on each side of the cross head.

these plates al projects considerably in front of the other as shown,and the forward portions are preferably serrated.

The turning member 0 comprises a pivoted plate etowhich again is pivotedthe actual contact or operating member t.

The apparatus is shown operating an ingot or bloom g, which is square incross section.

The operation will be readily understood. Supposing the ingot g to beresting on the conveying rollers a, the forward portion of thecounterbalanced plate d is brought against the same and the contactmember gives the ingot a preliminary turn, the result being that itfalls over and depresses the forward end of the plate (Z upon which itrests, the action being similar to that illustrated in Figs. 8, 9 and 10in the drawing of my British Patent 113225.

The cross head 0 is then drawn back and the operating member f againpicks up the ingot g pushing it against the second plate (Z which holdsit for the second part of the motion; this is shown in Fig. 1.

The particular construction illustrated is one in which the forwardportion of the cross head 6 is so shaped that the angle of the ingotcomes against it after the said ingot has been turned through a secondangular distance amounting to only elf degrees. If the front of thecross head 7) were cut away or the plate d projected to a greaterextent, the ingot 9 would be turned through a second angular distance of90.

In many cases however it is necessaryto introduce the ingot at aparticular angle for the further rolling operations, and the caseillustrated isv the one where it is desired to introduce a square ingotheld up upon its angular point after it reaches a total turning movementof 135.

Referring to Fig. 2 this illustrates a modification in which in. placeof providing two separate counterbalanced plates (Z1 and on each side ofthe cross head, a counterbalanced plate (Z is provided on each side ofthe cross head Z). Each of these plates (Z is provided with adownwardlyprojecting serrated portion (Z into contact with which the ingot g isfirst brought and with a second serrated portion (1 into contact withwhich the ingot g is brought for the second stage of the turning. y

In the modification as embraced in Figs. 3, l, and 5 the device isadapted for giving a larger range of turning movement for the ingot orbloom, the receiving or holding member being of the ordinarycounterbalanced type. Y

72 is a plate which in this case forms the turning clutch-member, whichis pivotally supported in position upon pivots 7c and q in workingprovided in the casing'of the head.

By means of this construction, with the parts in the position as shownat Fig. 3 when the turning clutch member is pressed against the ingot g,a preliminary turning .moyement takes place about the pivot m. Thiscontmues until the pivot lc has traveled to the end of the slot p asshown at Fig. 4:,

after which the clutch member pivots at /a, the ivot on traveling alongthe slot '9 until it reac ies the end thereof, as shown at Fig. 5 sothat a large turning movement is effected with a very simple operatingor turning clutch, in this case, consisting of a single member 01.

lVhere a greater range of movementis required, the turning member may bemade in two parts, as for instance as disclosed, in Fig. 6, wherein aplate It is provided mounted as previously explained with respect toFigs. 35 and which plate has mounted thereon the turning clutch proper7-.

lnsome cases in place of providing two separate pivots la and m'I mayprovide an arcuate projection S, at each side of the plate It. Thisarrangement is illustrated in Fig. 7 wherein Z refers to an arcuaterecess or slot formed in the-side of the casing of the cross head 0,adapted to receive said projections.

By means of this construction the end S of said projection first travelsalong to If, the end S acting as the pivot, after which the plate Itturns about the end S of said projections as a pivot, and the end Stravels along the bottom of the slot or recess until it reaches the end15 of the recess.

In the modification as disclosed by Figs. 8 and 9 is shown aconstruction which I may adopt in order to enable the receiving orholding and operating members to deal with ingots varying considerablyin cross section and especially suitable in addition for presenting theingot after the required amount of lturning at some particular angle tothe rol In this instance the receiving members carried by the cross headI) are constituted of plates (Z provided with forwardly projectingserrated portions cl and of another serrated portion (P located behindthe first mentioned portion 6 V The side plates (Z are also providedwith upwardly and forwardly projecting portions (Z d? as a distance baror piece connecting the side plates d (Z and d are proj ecting rods, oneach side of the head. The

lower rod (i works in a vertical slot 6 while the upper rod d works'inan angular slot 6 in the sideplate. r

Referring to. the construction just .described we will suppose that itis required to turn a small bloom square in cross section through 135and presentit on end to the rolls. At the commencement of operations,the rod d, which constitutes the turning pivot for .the plate d is atthe top'of the slot 6 and for the first turn effected by the forwardendal theparts remain in this position. After this turn has been effectedas the turning member pushes on the bloom, the upper edge thereof comesagainst the top wall of the recess a and the plates 03 are raised andthen the lower forward edge of the bloom comes against the serratedportion (5 of the plates (Z while at the same time the plates (Z slideupward owing to the provision of the slots 6 and b the parts coming intothe position shown in Fig. 9.

It will be evident that a considerable range of sizes may thus bemanipulated.

he operating member carried by the cross head 0 is mounted in a similarway, the plate it in the present case being provided with a pivot-pin ariding up slots 0 in the casing 0.

It will be evident that the shape of the inner portion of the receivingor holding member must be modified according to the form in the ingot tobe turned and held upright.

For instance if the ingot g were of oval form and it were applied topresent the ingot to the rolls with the major axis of the ingot in avertical position, the receiving plates in place of being shaped asshown at Fig. 9 would be of semi-elliptical shape as at (i In themodifications as disclosed by Figs. l0 and 11 are shown two forms ofplates for receiving various sections and giving them a turn in twostages, the serrated portion al first coming into action as previouslyexplained, after which the part al comes into action to give a secondamount of turn or to hold the ingot in some desired position in order topresent it as required to the rolls. Where necessary the plates are somounted with respect to the forward portion of the cross head 6 thatsuch portion cooperates.

with the counterbalanced plate or plates to hold the ingot in therequired position.
